摘　　要：以聚-4-甲基-1-戊烯(PMP)为泡沫骨架,μm量级钨为掺杂材料,超高分子量聚乙烯(UHWPE)为溶液粘度控制剂,通过热诱导倒相技术实现了低密度钨掺杂聚合物泡沫的制备。实验结果表明:当UHWPE质量分数为25%时,能够实现粒径10μm的钨在泡沫体内的均匀掺杂;泡沫密度为20mg/cm3时,钨掺杂质量分数最高可达60%。Low-density tungsten-doped poly（4-methyl-1-petene） （PMP） polymer foams were prepared with thermal induced phase inversion method using PMP as the foam skeleton material,tungsten in micron dimension as doping materials,and upper ultra-high molecular weight polyethylene（UHWPE） as solution viscosity control agent.The results indicated that 10-μm tungsten particle doped foams were synthesized uniformly when the mass content of UHWPE was 25%.The density of foam was 20 mg/cm3,while the mass content of doped tungsten reached up to 60 %.
